zweirad-stadler:bulls-sonic-evo-am-1-e-bike-mountainbike-fully-29-27-5-gelb · source URL · confidence 1

Eligibility

Cannot win: e-bike bikes are not value-ranked yet (no e-bike-specific equipment model)

Size decisions

A shopper asking for: 54 → nothing compatible · 56 → nothing compatible · 58 → nothing compatible · 60 → nothing compatible

Identity

Canonical configuration: Bulls | Sonic EVO AM 1 E-Bike Mountainbike Fully 29"-27.5" | CUES
Confidence: medium

• brand exact (Bulls)
• model normalized to "sonic evo am 1 e mountainbike fully 29 27.5"
• groupset family exact (CUES)
• model year unavailable on every listing
• 2 listings across 1 retailer
• downgraded to medium: no shared GTIN, and no listing states a model year

Provenance — why we believe each fact

Warnings

• info wheel-size-varies-by-frame-size — the row states more than one wheel size ("29"-27.5""), so the wheel size of the bike in a given frame size is not established. Recorded as unknown rather than picking one.
• info suspicious-discount — Claimed 46% off. Treated as context only; it does not affect the ranking.
